WINDOW REGULATOR.

Application filed December 26, 1924. Serial No. 758,085.

This invention relates to window regulators and has for its object a non-rattling coupling between the lever arm of the regulator and the window bracket.

A lever type of window regulator which has a sliding connection with a window channel bracket is old, and common in the art.

However, it is rather difficult to fit the roller in the track on the sash channel or fitthe button in a slot in the sash bracket so that it is not loose enough to rattle.

The object of the present invention is to provide an auxiliary yieldable bearing member that acts as an anti-rattler.

In the drawings:

Fi 1 is a fragmentary elevation of a coupe fitted with lever type of window reguiator.

lower sash bar, or what is usually called the window channel. Ne prefer to employ a single strip window channel that forms the sash bar a and a track or groove 7) for the roller 0 of the lifting arm d. This lifting arm cl can be raised or lowered by any form ment of mechanism, but preferably the segis provided near its fulcrum. This can be actuated by a driving pinion f. This is a familiar form of regulator now quite extensively used.

However, it is found in actual practice that it is not possible to'fit the roller 0 into the groove or track so that it is order absolutely free from rattling. In to obviate this trouble, we rivet to the end of the arm a spring-bearing strip h.

This

is provided with a struck-out lug i which projects through the slot j in the The end of this hearing strip is provided with an enlarged head 70 in the form of a ring arranged to fit over the shank or hub 70 of the roller button 0 before that member is riveted to the lifting arm d.

This forms a very convenient spring-bearing strip, inasmuch as this is angularly disposed in respect to the lifting arm; consequently ordinarily only the outer end of the ring will bear against the sash bar or the window bracket. Hence there is very little rubbing action so as to eliminate friction and lost effort. ()n the other hand, this is sufficient to hold the parts from drumming or rattling, due to the vibration of the car. Furthermore, this form of yieldable bearing strip is also a very convenient one in assembling the parts together. The form of sash here shown is assembled to the roller by removing the moulding a? and tipping the sash inwardly. The spring bearing strip may easily yield clear down to the lifting arm stock to permit the parts to be shifted about in this assembling operation.

IV hat we claim is:

1. In a window regulator, the combination of a sash bar provided with a track or recess, a lifting arm having a roller running in said track or recess, and a flat spring supported on the end of the arm and between the roller and the lever and arranged to bear against the track.

2. In a window regulator, the combination of a sash bar provided with a track or groove, a lifting arm provided with a roller having a shank and arranged to run in said track or groove, and a yieldable bearing strip secured to the end of the arm and having a ring port-ion at its end fitting over the shank of the roller to act as an anti-rattling member.

In testimony whereof we have afiixed our signatures.
